Aha!  Using the "--initrd" option on the make-kpkg worked very neatly.
Thank you.

Probably, but not in my case.  I use Debian because I rarely need to
think about kernels, or drivers, or anything at all - apt-get and go.
However, I needed the kernel headers to get my Wacom tablet working (I
used this guide: and I could
not apt-get the headers for my kernel anymore, so I needed a new kernel
for the headers to relate to.  I never used to make an initrd, but now I
seem to need to.  Live and learn.
